DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a display system, a display method, and a storage medium of the present invention will be described. The display system of this embodiment is applied to a digital image printing system.
[0020]
[First Embodiment]
FIG. 1 is a diagram showing a configuration of a digital image print system according to the first embodiment. The digital image print system 1 includes a digital image print adapter device 3, a user operation remote controller 5, a TV device 6 that displays an image, and a printer 8 that performs printing. The user operation remote controller 5 is provided with operation buttons 5b and a display panel (LCD panel) 5a.
[0021]
FIG. 2 is a block diagram showing the configuration of the digital image print adapter device 3. The digital image print adapter apparatus 3 is supplied from a ROM 11 that stores programs and data, a CPU 12 that performs processing according to the processing procedure of the programs stored in the ROM 11, a RAM 14 that holds intermediate information necessary for processing, and the like. An image information holding unit 17 that holds image information and the like, an image information communication unit 18, and a printer interface 19 for outputting to a printer are connected via a bus 15. In addition, the bus 15 includes a user operation input unit (operation button) 5b that receives a user operation, a first display device (display panel) 5a that immediately displays an operation state to the user, and a first display device. A second display device (TV device) 6 is connected to display images, characters, and the like because the display process takes time. The printer interface 19 is connected to the printer 8 described above.
[0022]
In the digital image print system having such a configuration, image information supplied from an external device (not shown) such as a digital camera or a memory card (not shown) connected via the image information communication unit 8 is Once held in the image information holding unit 17. When a user operation is received from the user operation input unit 5b, processing corresponding to the operation is performed. For example, image information is sent to the printer 8 for printing, the status of the apparatus is displayed on the display panel 5a, or the TV apparatus 6 is displayed. An image can be displayed on the screen.
[0023]
FIG. 3 is a flowchart showing a display processing procedure for a user operation. This processing program is stored in the ROM 11 and is executed by the CPU 12. After startup, first, the system is initialized (step S1), and an input of a user operation is accepted (step S2). After performing the process of changing the state of the apparatus in response to the user operation (step S3), the display process for the first display apparatus (LCD panel) 5a is performed (step S4).
[0024]
Subsequently, preparation for display processing is performed for the second display device (TV device) 6 that does not take time for display processing (step S5). Then, it is determined whether or not it is possible to execute display processing that does not take time for the second display device (step S6). If the display process can be executed, the display process that does not take time for the second display device is performed (step S7). On the other hand, even if the process does not take time to display such as cursor display, if the exact cursor position cannot be obtained without the information of the image displayed there, just set the display request flag to ON. Display processing is not performed (step S8). Thereafter, preparation for display processing for the second display device, which takes time, is performed (step S9).
[0025]
While performing the time-consuming display process for the second display device, the input of the next user operation is confirmed. That is, the input of the user operation is checked (step S10), it is determined whether or not there is a next user operation (step S11), and if there is a next user operation, the process returns to step S3 again for the user operation. The device state changing process is performed accordingly. On the other hand, if there is no input from the next user operation, a part of the time-consuming display process for the second display device is executed (step S12). Thereafter, it is determined whether or not all time-consuming display processing for the second display device has been completed (step S13), and if not all have been completed, the process returns to step S10 to check the input of the user operation.
[0026]
On the other hand, when all the time-consuming display processing for the second display device is completed, it is determined whether or not the display request flag is set to ON (step S14), and the display request flag is not set to ON. Returning to the process of step S2, on the other hand, when the display request flag is set to ON, a display process that does not take time for the second display device is executed (step S15). Thereafter, the process returns to step S2. Thus, the display process for the second display device is performed to the end.
[0027]
Thus, the display processing for the first and second display devices that do not take a long time for the display processing, the display processing for the second display device that takes a long time for the display processing, and the display processing for which the two are related to each other are contradictory. By executing without executing, the first display processing for the first display device can be performed as soon as possible regardless of the display processing time for the second display device, and can be displayed to the user in real time.
[0028]
In the present embodiment, the time-consuming display process for the second display device, which is executed in step S12 when there is no user operation input in step S11, is the latest among the processes waiting to be processed. Only things are executed.
[0029]
[Second Embodiment]
Since the digital image printing system in the second embodiment has the same configuration as that of the first embodiment, the description thereof will be omitted, and only the display processing in the second embodiment will be described. In the second embodiment, the display processing is divided for each task, and the display processing is performed according to the priority order of the tasks.
[0030]
FIG. 4 is a flowchart showing a display processing procedure in the second embodiment. This processing program is stored in the ROM 11 and is executed by the CPU 12. After startup, first, initialization processing is performed (step S21). An input of a user operation is accepted (step S22). After the apparatus state changing process corresponding to the received user operation is performed (step S23), the display process for the first display apparatus that does not take time for the display process is performed (step S24).
[0031]
Subsequently, preparation for display processing which does not take time for the second display device is performed (step S25). Whether or not display processing that does not take time for the second display device can be executed, that is, in order to execute this display processing, time-consuming display processing for the next second display device needs to be executed. It is determined whether or not there is (step S26). If it is not necessary to execute the time-consuming display process for the next second display device, the time-consuming display process for the second display device is executed (step S27). On the other hand, when the time-consuming display process for the next second display device needs to be executed, the display process request flag is only set to ON and the display process is not performed (step S28).
[0032]
Then, a display execution request is issued to the second display device that is expected to take a long time for the display process (step S29), and the process returns to step S22 to accept the input of the user operation. The issued display execution requests are stored in the display execution request holding area allocated to the RAM 14 in the order of issue.
[0033]
FIG. 5 is a flowchart showing a display processing procedure for the second display device. This processing program is stored in the ROM 11 and is executed by the CPU 12. First, a display execution request is checked (step S31), and the process of step S31 is repeated until the latest display execution request is extracted (step S32). When the latest display execution request is extracted, a time-consuming display process for the requested second display device is executed in accordance with the extracted latest display execution request (step S33).
[0034]
Next, as a result of the determination in step S26 of FIG. 4, it is determined whether or not there is a display process that does not take time for the second display device that could not be executed, that is, whether or not the display process request flag is set to ON in step S28. (Step S34), and when the display processing request flag is set to ON, the display processing for the second display device is performed in a time-consuming manner to arrange the screen of the second display device, and then the step is again performed. Returning to S31, the presence or absence of a display execution request is checked. On the other hand, if the display process request flag is OFF in step S34, the process directly returns to step S31.
[0035]
The display processes of FIGS. 4 and 5 are executed in an independent context, but the display process of FIG. 4 has a higher priority. Accordingly, even when the display process of FIG. 5 is being performed, if there is an operation by the user, the display process of FIG. 5 is interrupted, the display process of FIG. 4 is executed, and the display process of FIG. The display execution request by the user operation is held in the display execution request holding area.
[0036]
In addition, the display processing of FIG. 4 always displays the first display device in real time with respect to the user operation, and it can be avoided that the display response to the user operation is delayed due to the time-consuming display processing.
[0037]
In the display process of FIG. 5, the time-consuming display process for the second display device is divided into finer units, and each time a display execution request is checked, a display switching response to the second display device is obtained. It is also possible to increase the speed. In this case, it is possible to execute the processing procedure of FIG. 5 just by determining the subdivision rule of the display unit.
[0038]
In addition, when there are multiple display modes and the time required for display processing differs in each display mode, display processing that does not take time is processed at once, and time-consuming display processing is performed by dividing the processing. It is also possible to make the display response speed uniform between the modes.
[0039]
In addition, if you have multiple display modes and want to increase the response speed when transitioning between display modes, after subdividing the display processing, each time a processing mode change request is detected and changed. If this happens, the next display execution request may be immediately processed.
[0040]
In addition, when moving from one mode to another mode, after completing the display of the previous mode, if there is a request for mode switching in the request check during display processing in a mode, the request is changed to The display may be performed while being held, and the mode switching process may be performed within the initial request determination process.
[0041]
Furthermore, in the above embodiment, the first display device is an LCD panel, and the second display device is a TV device, but other combinations, for example, PDP, LED, buzzer, CRT display, LCD panel capable of displaying images A combination of these may be used. Further, the screen may be divided into a plurality of areas, and a combination of an area that displays a long display time and an area that does not display it may be used.
[0042]
Moreover, although the case where it has two display apparatuses was shown in the said embodiment, even when it has three or more display apparatuses, this invention is applicable similarly.
[0043]
Further, the present invention may be applied to a system constituted by a plurality of devices, or may be applied to an apparatus constituted by one device. Needless to say, the present invention can also be applied to a case where the present invention is achieved by supplying a program to a system or apparatus. In this case, the system or apparatus can enjoy the effects of the present invention by reading the storage medium storing the program represented by the software for achieving the present invention into the system or apparatus.
[0044]
FIG. 6 is a diagram showing a memory map of the ROM 11 as a storage medium. The ROM 11 stores a display processing program module shown in the flowchart of FIG. 3, a display processing program module shown in the flowchart of FIG. 4, a display processing program module for the second display device shown in the flowchart of FIG.
[0045]
The storage medium for supplying the program module is not limited to the ROM, but, for example, a floppy (registered trademark) disk, hard disk, optical disk, magneto-optical disk, CD-ROM, CD-R, DVD, magnetic tape, nonvolatile memory card, etc. Can be used.
[0046]
【The invention's effect】
According to the present invention, when a time-consuming display process is performed on the first display device and a time-consuming display process is performed on the second display device, a second user operation is performed. By canceling the time-consuming display processing on the display device, the display processing on the first display device is performed as soon as possible without relying on the time-consuming display processing on the second display device, so that the user can It is possible to build a system that can display on the screen.
[0047]
Therefore, when an image is displayed for a user operation using the first display device having a short display processing time and the second display device having a long display processing time, a satisfactory operation feeling can be obtained.
